Chroma Club has announced Zoo Club – the firm's Android release based on the free eBook Chroma Club: The Zoo - has just passed 1 million installs on Google's platform.

As a result, Chroma Club has revealed it's looking to port versions of the app both to iOS, and Barnes & Noble's Android-equipped Nook e-readers.

Zoo Club pitches itself as the top free zoo release on the platform, offering players the opportunity to maintain their own park as well as take on a selection of mini-games.

The title is currently part of a daily Chroma Club competition, which gives away glow-in-the-dark bracelets to players who purchase a ticket in-game.

The app also offers additional features if users become a member of the Chroma Club, though the firm hasn't released statistics detailing the number of members who have signed up to date.
